The degradation of forest ecosystems has also been traced to economic incentives that make forest conversion appear more profitable than forest conservation. [125] Many important forest functions have no markets, and hence, no economic value that is readily apparent to the forests' owners or the communities that rely on forests for their well ...
From the approximately 16 million square kilometers of tropical rainforest habitat that originally existed worldwide, less than 9 million square kilometers remain today. [7] The current rate of deforestation is 160,000 square kilometers per year, which equates to a loss of approximately 1% of original forest habitat each year. [10]
Bolivia also has the seventh largest amount of tropical rainforest. Overall, forests made up 51.4 million hectares or 46.8% of the country's total area as of 2013. [143] Both primary forest and overall forest cover have been declining in recent decades. [143]
Monitoring of wildlife populations is an important part of conservation because it allows managers to gather information about the status of threatened species and to measure the effectiveness of management strategies. Monitoring can be local, regional, or range-wide, and can include one or many distinct populations.
Deforestation in the Maranhão state, Brazil, in July 2016. The Amazon rainforest, spanning an area of 3,000,000 km 2 (1,200,000 sq mi), is the world's largest rainforest.It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests.
An important consideration in such efforts is that forests can turn from sinks to carbon sources. [42] [43] [44] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [45] and deforestation. The typical tropical forest may become a carbon source by the 2060s. [46]
Degraded forest in Lahnberge, Germany: the soil is being washed out due to lack of vegetal cover, some trees are losing ground and they appear to be sick (photo by Andreas Trepte). Forest degradation is a process in which the biological wealth of a forest area is permanently diminished by some factor or by a combination of factors. "This does ...
Reforestation is not only used for recovery of accidentally destroyed forests. In some countries, such as Finland, many of the forests are managed by the wood products and pulp and paper industry. In such an arrangement, like other crops, trees are planted to replace those that have been cut.
